I enjoy reading good books, but even when I don’t have time for that I try to keep up with my favourite web comics at least.
Headtrip is a funny comic series with several recurring characters and different story lines. The humour is a bit biting at times. Geeky, but not a lot of background knowledge required. I really like it :D No clue about the current scheduling of new comics, though. There used to be one. http://headtrip.keenspot.com/
CAD has also several recurring casts and story lines. Sadly the main story line for which I loved reading it has ended, but there are other ones coming up now. New comics come out on Mondays, Wednesdays, and Fridays. http://www.cad-comic.com/cad/
Fisheye Placebo … amazing stuff. Put together great artistic talent and a questioning mind, and you get a nice view on the fight against a future surveillance state. It’s a work in progress and I’m desperately waiting for new chapters all the time! There is no schedule for posting, I think. http://tapastic.com/series/fisheye#!/series/episodes/347/1/asc
I’m not sure if Pull Down Heaven qualifies as a comic as there is next to no understandable speech in it. But it is really beautiful. There is a whole lot of pages online already. (I hope the link works. If not, please tell me, or just go to deviantART and search for it, it’s easy to find.) http://moonsongwolf.deviantart.com/art/Pull-Down-Heaven-01-155341161
